removal from wastewater is an increasingly common requirement for water resource recovery facilities (WRRF) and nitrogenandphosphorus are the nutrients being targeted. Utilities are being encouraged to remove as much nitrogen as possible to comply

Elimination System (NPDES) created by the Environmental Protection Agency. The system tracks everything from nitrogenandphosphorus limits to dissolved oxygen minimums, which have an impact on aquatic life. The Mooney AWRF frequently does better

which it inevitably is in the summertime, he uses an innovative multi-barrier approach to eliminate it. Excess nitrogenandphosphorus cause an overgrowth of algae in a short period of time, faster than ecosystems can handle. Seen here, an algal

Water Act," he said. Arndt noted that cyanotoxin contamination is always associated with excessive amounts of nitrogenandphosphorus in water. Further, he said the U.S. Geological Survey has estimated that non-point sources, predominantly

create compelling visualizations that inform citizens, communities and resource managers about conditions of nitrogenandphosphorus in the nation's waters. The goal of Visualizing Nutrients is to help educate and inspire action to address
